Networking architectures have grown increasingly complex, where their underlying architectures have been designed for use in a wide variety of communications environments. Demand continues to rise among the subscriber base of end users for reliable network access across network environments. In particular, configuring suitable network architecture for vehicular environments (e.g., automobiles, airplanes, trains, boats, etc.) presents unique difficulties. For example, vehicles can be found across a large geographic area and may need to communicate with both fixed and roaming external nodes, as well as communicate with intra-vehicle devices over internal networks. Furthermore, communications may be hampered by intentional and/or incidental interferences, cost factors, as well as power-related limitations. Thus, providing the ability for vehicles to communicate in vehicular network environments in a reliable, cost-effective, and power-conscious manner presents significant challenges to system designers, automobile manufacturers, service providers, and the like.
